Abstract: A roller cutter has a partially circular housing having a slit extending in from receiving a cutter wheel, which can be selectively shifted between an extended cutting position and a retracted position enclosed within the housing to protect the cutter wheel cutting edge. A push button operates a latch release to allow shifting between these positions. A slide bar mounting the cutting wheel for shifting movement is itself held in a slot in the housing, but may be released for removal and cleaning. A tangential grip at the top of housing allows convenient stroking for cutting pizza, mincing herbs, etc.

A distal beveled face and a third guide face are formed between the first side and the second side of the distal end.

Abstract: A drywall cutting tool provides cuts in drywall material either parallel or perpendicular to a reference edge of the sheet, without repositioning the tool from the reference edge. The tool comprises a T square, with the head and stem portions immovably affixed to one another. The stem of the tool carries a slidably adjustable cutting body thereon, with the cutting body being secured through an elongate slot formed in the center of the stem portion of the device. The cutting body carries a pair of spaced apart cutting rollers or discs, and may be turned so the cutting axes of the two discs define a line either parallel or perpendicular to the reference edge of the sheet, and thus perpendicular or parallel to the stem of the tool.

Abstract: The present invention preferably employs non-contact, small-displacement, capacitive sensors to determine Abbe errors due to the pitch, yaw, or roll of a near linear mechanical stage that are not indicated by an on-axis position indicator, such as a linear scale encoder or laser interferometer. The system is calibrated against a precise reference standard so the corrections depend only on sensing small changes in the sensor readings and not on absolute accuracy of the sensor readings. Although the present invention is preferred for use in split-axis positioning systems with inertially separated stages, the invention can be employed in typical split-axis or stacked stage systems to reduce their manufacturing costs.

Abstract: An alignment system for directing the generated output of a sound, light source, or visual device from a loud speaker, light generator or camera to a specifically selected target area wherein the system includes a precision laser generator carried on a selected end of a body for generating a linear laser beam.

By employing the variable adjustment beams, the interaction between the generated beam and sound waves and an existing room geometry can be visually observed. The adjustable means produces a laser line at variable fan angles to match reference beam or wave dispersion angles.

Abstract: A fish tape with one-foot increments affixed to its surface using a laser.

Abstract: The present invention relates to a drawing apparatus specifically one that allows the user to generate smooth arced and curved lines. The present invention has the advantage to allow the user to create unique arcs and curved lines, rather than follow predetermined templates. The present invention also increases the quality of work because the present invention allows for a unique curve to be created, while French curve templates often require several predetermined templates and curves to be used in combination to create a desired curve. The present invention allows for a unique curve to be saved by tightening the guide track into a locked position. Furthermore the present invention allows for a unique curve to be metered and replicated again at a later time.

Abstract: A short bolt rifle that enables increased barrel without an increase in weight. A longer barrel increases bullet velocity, which increases the range and accuracy of the weapon and the bullet impact energy. In this action, the bolt is simply pulled back and pushed forward. The design includes a loader mechanism that ejects spent cartridges and loads a new cartridge. This happens while the bolt is drawn back and pushed forward. A rotating lock secures the bolt in the firing position. A second version of the action uses a pistol grip. A lock holds the pistol grip, which can be released. After it is released, the user pulls down and back on the grip to open the action. The grip is pushed forward and upward, to load a shell, while the bolt is moved forward and locked. The action also can easily be adapted to fully automatic operation.

The data mechanically encoded preferably include redundant bits which provide error control coding, thereby making identification both easier and more certain. The pattern is preferably formed by a mechanically-invariant process (such as EDM or photoengraving).

Abstract: The invention relates to a method for making a building board, exhibiting a board body which is formed with a gripping stud, and a metal strip which extends from the body and from which are formed gripping elements, which are bent round the gripping stud for mechanical fastening of the strip to the body, as well as a locking element for enabling mechanical joining of the board to similar boards. The method is characterized by preforming the gripping elements of the strip prior to bending them round the gripping stud, and subsequently bending the preformed gripping elements ground the gripping stud, the preforming being such that, as a result of the bending, the preformed gripping elements strike against the gripping stud and thereby undergo a deformation in the opposite direction to the preforming during a final stage of the bending.
